Read only position from metadata

Browse Source 
We now determine whether this is a global or an extruder profile based on whether the position metadata field is present, instead of whether the extruder metadata field is present.

Contributes to issue CURA-5054.

# TODO: in 3.2 and earlier, a quality_changes container may have a field called "extruder" which contains the
# extruder definition ID it belongs to. But, in fact, we only need to know the following things:
# 1. which machine a custom profile is suitable for,
# 2. if this profile is for the GlobalStack,
# 3. if this profile is for an ExtruderStack and which one (the position).

# So, it is preferred to have a field like this:
# extruder_position = 1
# instead of this:
# extruder = custom_extruder_1

# An upgrade needs to be done if we want to do it this way. Before that, we use the extruder's definition
# to figure out its position.
